Python: Merge two lists of dictionaries

Question

Given two lists of dictionaries:

>>> lst1 = [{id: 1, x: \"one\"},{id: 2, x: \"two\"}]
>>> lst2 = [{id: 2, x: \"two\"}, {id: 3, x: \"three\"         


        

Answer 1

lst1 = [{"id": 1, "x": "one"}, {"id": 2, "x": "two"}]
lst2 = [{"id": 2, "x": "two"}, {"id": 3, "x": "three"}]

result = []
lst1.extend(lst2)
for myDict in lst1:
    if myDict not in result:
        result.append(myDict)
print result

Output

[{'x': 'one', 'id': 1}, {'x': 'two', 'id': 2}, {'x': 'three', 'id': 3}]
